  • ⁇ preservatives e.g., Mergal K9N ® (Riedel) or Cobate C ® or l,2-Benzisothiazolin-3-on (or its sodium salt).
  • liquid formulations or suspensions of the invention can be prepared by methods which are customary in principle, i.e., by mixing the components with stirring or shaking or by means of static mixing methods.
  • the liquid formulations obtained are stable with good storage properties.
  • the liquid formulations comprising active ingredient and the adjuvant formulations are low-foam formulations with good storage properties. In many cases they have very favorable technical properties on application.
  • the formulations are distinguished by a low tendency to aggregate, e.g. during storage, Accordingly the formulations of the invention are especially suitable for use in crop protection where the formulations are applied to the plants, to parts of plants or to the area under cultivation.
  • the formulations are very suitable for controlling unwanted plant growth both on uncultivated land and in tolerant crops.
